Which statement best describes the relationship between desertification and crop production? question 7 options: desertification increases the amount of crops produced. desertification does not impact crop production. desertification increases the speed of crop production. desertification decreases the amount of crop produced.

The correct answer is D. Desertification decreases the amount of crop produced.

Explanation

Desertification is the process through which fertile lands lose their productive capacity until they become naturally unproductive and desert lands. Desertification can occur due to natural processes or human activities such as deforestation, monoculture, bad agricultural practices, irresponsible water management, overgrazing, among others.  Additionally, if desertification occurs in a previous fertile land that was used for crops it is common the production of crops decreases as soil that has gone through this process losses minerals, water, and nutrients that are necessary to grow crops. So, the correct answer is D. Desertification decreases the amount of crop produced.

answer: c. the experiment shows that the red substance experienced a chemical change.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
